The Opportunity

Problem

Local communities facing uncertain negative impacts from AI-driven data center boom

Solution

Impactly is an interactive simulator that lets any resident or leader model the specific effects of a proposed data center on their commune. Using localized French meteorological, grid, and demographic data, it visualizes outcomes for power prices, water consumption, heat islands, traffic, and jobs. Results can be exported as authoritative visuals for public hearings.

Target Audience

Residents and local leaders in French regions targeted for new data centers

Differentiator

Only simulator using France-specific datasets (Météo France, RTE grid data, BRGM water tables) for credible hyper-local forecasts instead of generic global assumptions.

Electricity price impact on households
Water table stress visualization
Professional visuals for officials

Social Proof (Placeholders)

"'The simulation I created was shown on the big screen at the public meeting. It changed the entire discussion.' — Sophie Moreau, Elected official in Marne"
"Finally a tool that makes technical data accessible to normal citizens.' — Climate activist, Grand Est"

First Three Customers

Partner with three scientists or engineers already active in local data center opposition groups (easily found on LinkedIn and Twitter) and give them free Enterprise access in exchange for public case studies. Present the tool at the next public inquiry meeting for a proposed project. Offer free access to the first three communes that have an active consultation if their mayor agrees to mention the tool in official communications.

Competitive Analysis

En-ROADS

en-roads.org
Free
Strength

Excellent climate modeling

Weakness

Too high-level, no hyper-local French infrastructure data

Our Advantage

Built specifically for French communes with RTE and BRGM datasets

🏰 Moat Strategy

Extensive curated dataset of French-specific multipliers and real-world calibration from past projects. Users contribute new calibration data after projects are built.

⏰ Why Now?

Multiple competing data center projects are being announced in the same regions simultaneously, forcing communes to rapidly compare proposals using credible numbers.

Risks & Mitigation

technicalmedium severity

Simulation model accuracy questioned

Mitigation

Publish methodology openly and allow community calibration with real post-construction data

marketlow severity

Users prefer simple narratives over data

Mitigation

Provide both one-click 'advocacy mode' and detailed scientific mode

Validation Roadmap

pre-build12 days

Create paper prototype and test with 12 local council members

Success: At least 9 say they would use it in upcoming public inquiries

mvp30 days

Launch closed beta to users from first idea's waitlist

Success: 25% of beta users run 5+ simulations

Pivot Options

  • Become the standard ESG modeling tool for European data center developers
  • Expand into full infrastructure project comparison platform (nuclear, solar, battery storage)
